Applicator device for applying a product of fluid or pasty type to keratin fibers

Abstract

The application relates to an applicator device for applying a product of the fluid or pasty type to keratin fibres or to an epidermis, including a central core of elongate shape, which extends along a longitudinal axis XX, at least one row of elongate spikes including a first end embedded in the core and a second, free end, the spikes and the core being formed in one piece, at least one of the spikes being delimited by a first flat face coincident with a longitudinal plane passing through the longitudinal axis XX of the central core, referred to as the joint face, and by a second flat face that forms, with the first flat face, an angle of between 91° and 179°, delimiting a cosmetic product reservoir volume V.

         14 . An applicator device for applying a product of fluid or pasty type to keratin fibers or to the skin, comprising:
 an elongate central core, the elongate central core extending along a longitudinal axis XX, and   at least one row of elongate spikes comprising a first end embedded in the elongate central core and a free second end,   wherein the spikes and the elongate central core are made in one piece,   wherein at least one of the spikes is delimited by a first flat face which coincides with a longitudinal plane passing through the longitudinal axis XX of the central core, referred to as joint plane, and by a second flat face forming a first angle with said first flat face of between 91° and 179°, and   wherein the arrangement of the first and second flat face delimiting a reservoir volume V for cosmetic product.   
     
     
         15 . The applicator device as claimed in  claim 14 , wherein the at least one of the face includes a third flat face forming a second angle with the first flat face of between 1° and a value complementary to 180° of the first angle minus 1°, the third flat face delimiting the reservoir volume V for cosmetic product that takes the form of a longitudinal groove. 
     
     
         16 . The applicator device as claimed in  claim 14 , wherein the at least one spike has a frustoconical shape and includes a first and second adjacent frustoconical sections, the second frustoconical section having an overthickness in relation to the first frustoconical section, with a longitudinal rim separating the two frustoconical sections. 
     
     
         17 . The applicator device as claimed in  claim 14 , wherein the wherein the at least one spike has a frustoconical shape, the free end of the at least one spike having a frustoconical part with an overthickness in relation to the rest of the at least one spike, the at least one spike further including an annular rim separating the frustoconical part with an overthickness from the rest of the at least one spike. 
     
     
         18 . The applicator device as claimed in  claim 14 , wherein the at least one spike has first and second parts superposed, over some of each of their heights, one on the other along a longitudinal axis of the at least one spike, the first part being delimited by the first and second flat faces, the second part protruding from the first part. 
     
     
         19 . The applicator device as claimed in  claim 18 , wherein the second part has an overall shape which is mirror-symmetrical in relation to the first part. 
     
     
         20 . The applicator device as claimed in  claim 18 , wherein the second part is superposed entirely over some of the height of the first part, between ends of the first part. 
     
     
         21 . The applicator device as claimed in  claim 18 , wherein the at least one spike has a third part superposed on the second part over some of each of their heights, one on the other along a longitudinal axis of the spike, the third part protruding from the second part. 
     
     
         22 . The applicator device as claimed in  claim 14 , wherein the at least one spike has elements protruding from an outer surface of the at least one spike. 
     
     
         23 . The applicator device as claimed in  claim 14 , wherein the at least one spike has elements that are extending recessed from an outer surface of the spike. 
     
     
         24 . The applicator device as claimed in  claim 14 , wherein at least two of the spikes making up a row and including the at least one spike have an identical orientation. 
     
     
         25 . The applicator device as claimed in  claim 14 , wherein at least two of the spikes making up a row and including the at least one spike have a different orientation. 
     
     
         26 . The applicator device as claimed in  claim 14 , wherein the distance measured along the axis XX between two successive spikes of the at least one row is zero or positive. 
     
     
         27 . The applicator device as claimed in  claim 26 , wherein the distance measured along the axis XX between two successive spikes of the at least one row is less than approximately 2 millimeters.
